Abstract

Magnetorheological fluids (MRFs) on a basis of synthetic oils and carbonyl iron were synthesized and studied. It was found that introduction of the appropriate stabilizer plays an important role in formation of usable magnetorheological properties. For the MRFs, synthesized in this study, the shear modules, obtained in a magnetic field of 159 kA/m, were as follows: complex shear modulus G^* - 1.2 MPa, storage modulus G´-1.2 MPa and loss modulus G” -0.35 MPa. The MRFs were applied as a component of the composite passive armour. The application of the magnetic field for such structures results in improvement of the protective properties of the armour.
